HMEYMIM (Syria), June 10. /TASS/. Militants of the Jabhat al-Nusra terrorist organization keep firing mortar shells at a Kurdish neighborhood of Sheikh Maqsood in Syria’s Aleppo, a representative for Russia’s center for reconciliation of the warring parties in Syria said on Friday.

"Mortar shellings of a Kurdish neighborhood of Sheikh Maqsood in the northern part of Aleppo by the Jabhat al-Nusra gunmen have not ended. Terrorists are opening fire on the streets of the district from an area of the Kastello shopping center earlier held by the moderate opposition forces," the representative said.

The shellings target both the positions of government forces and the Kurdish militias, and the residential houses of civilians, he added.

The militants also fired mortar shells at the settlement of Handrat in Syria’s Aleppo province.

According to the spokesman, militants have also attacked the positions of the Syrian army in the settlement of Ansar on the southern outskirts of Aleppo.

"The position of the government forces were attacked by groups of militants from terrorist organization on the southern outskirts of Aleppo, in the settlement of Ansar," the spokesman said.

He added that militants used small arms, grenade launchers, mortars and anti-aircraft guns.

Several settlements were shelled from mortars and multiple rocket launcher systems in the province of Aleppo over the last 24 hours. According to the center for reconciliation, 54 civilians were killed and 93 more injured.

Heavy fighting with use of armored vehicles has been underway in the Aleppo province for the last several days. The center for reconciliation noted that militants took advantage of the regime of cessation of hostilities and close proximity to regions controlled by moderate opposition, regrouped their forces and replenished their stocks of arms and ammunition.

The ceasefire regime took effect in Syria on February 27. Shortly before, the UN Security Council adopted a resolution supporting a cessation of hostilities. The document drafted by Russia and the United States was backed by all 15 Security Council member states.

The ceasefire regime does not cover the Islamic State and Jabhat al-Nusra terrorist organizations as well as other groups ruled terrorist by the UN Security Council.
